Notes on using RG-174 Coaxial Cable at Medium and Lower HF Frequencies with Assembling RG-174 BNC Connectors

COAX DE-RATING for SWR, temperature, gives temperature rise, much more. Remember Power handling capacity in watts is inversely proportional to SWR.

From the Wirebook IV, pages 3.2 and 3.3
Alan Bloom, N1AL, used an HP8753 RF network analyzer to compare losses of UHF vs. N connectors.
Both connectors measured 0 db loss up to 100 MHz.
At 150 MHz, the N has 0 db loss, the UHF has .01 db loss.
At 450 MHz, the N has 0 db loss, the UHF has .09 db loss.
Other studies show similar results -- Ed

Bullet Proof Phones. This from K6LL. Try the $15 Radioshack Model ET-296 series, catalog # 43-874 (white). It comes in several colors with slightly different catalog numbers. I haven't tried it personally, but it sure looks just like the old 43-591. Another phone that has proved to be 100% bulletproof here is the Uniden Model EXP 970. It is an 800 MHz cordless, available at Walmart for under $10, at least the last time I bought one, about a year ago. My xyl routinely chats on this phone for hours while I am in high power contests, with no complaints. One drawback to this phone for your application is that you will have to keep the battery charged, because it takes several hours for the initial charge. This phone also sounds great and has a 10 number dialing memory.
